Title: Heat transmission distribution measuring instrument utilizing temperature sensing liquid crystal
Inventor: AKINO NORIO
IPC: G01K11/12
Filed: 1987-08-11
Abstract: PURPOSE:To eliminate peeling due to a run and to take an accurate measurement by laminating an electric resistance layer for heat generation made of a transparent conductive film on the surface of a temperature sensing liquid crystal layer. CONSTITUTION:The electric resistance layer 3 for heat generation made of the transparent conductive film 5 is laminated on the surface of the temperature sensing liquid crystal layer 4. Further, the surface on the side of the liquid crystal layer 4 is adhered to a body 1 to be measured by using an adhesive 2. Then electrodes 6 are formed on the resistance layer 3 along both sides of the surface, an electric wire is fixed, and a power source 7 is connected. Here, a voltage is applied to generate heat and heat the body 1 to be measured, and thereafter air is blown to the surface for cooling, thereby observing the surface of the liquid crystal layer 4 through the resistance layer 3 in this state. Then the liquid crystal colors in dark brown as a low-temperature color on the upstream side, changes to higher-temperature colors in order toward the upstream side, and colors in Nile green uniformly in the nearly half area on the downstream side, so that the temperature distribution of the body 1 to be measured is accurately measured.

Title: Penetrant testing method for metal composite plate
Inventor: KAKIMOTO ETSUJI
IPC: G01N21/91
Filed: 1994-08-25
Abstract: PURPOSE: To easily detect the accurate position and the size of a defect existing in a joined part by cutting or polishing the boundary of a composite plate from the metal side having a relatively high hardness to the metal side having a relatively low hardness, and conducting penetrant testing. CONSTITUTION: When the arbitrary joined end face of two or more layers of metal composite plates made at least of metal materials having different hardnesses are penetrant-tested, the plates are cut or polished from the metal side having a relatively high hardness to the metal side having a relatively low hardness. Thus, the phenomenon in which the metal having the high hardness is deformed to be coated with a joined boundary is prevented and the designated pattern obtained by penetrant testing is made coincident with the defect existed in the boundary before the testing.  For example, in the case of the metal composite plate of titanium, steel or stainless steel and the steel, it is cut or polished from the titanium, the steel or the stainless steel side toward the copper side, and in the case of the metal composite plate of aluminum and copper, it is cut or polished from the copper side toward the aluminum side.

Title: Button type cell
Inventor: OYA KUNIYASU
IPC: H01M10/28
Filed: 1988-08-12
Abstract: PURPOSE:To prevent generation of deformation or cracks in a separator at a gap portion so as to minimize the self-discharge of a cell caused by short- circuiting in the cell by controlling the gap between a sealing gasket and a positive pellet or between a negative pellet and the same to be 10 times or less of the thickness of the separator. CONSTITUTION:This cell is structured such that the gap between the outer circumference of a positive or negative pellet of hydrogen storage alloy 5 disposed on the side where a part of a sealing gasket 4 exists and the inner circumference of the sealing gasket is controlled to be 10 times or less of the thickness of a separator 3. It is possible to prevent the separator from swelling up at the gap by minimizing the gap, and to prevent the generation of deformation or cracks resulting in enlargement of minute hole of the separator. Since possibility of fine substance such as powder composing an electrode to pass through the separator becomes less, short-circuiting phenomenon in the cell can be prevented and the self-discharge performance thereof can also be improved.

Title: Flexible printed-wiring board
Inventor: KODACHI YASUTOMO
IPC: H05K3/38
Filed: 1988-08-12
Abstract: PURPOSE:To enable a printed-wiring board to be manufactured in the process approximately equal to the ordinary one, and flare stopping property to be obtained sufficiently by adherence-laminating a conductive metallic foil on a film base material by an adhesive agent blended with flare stopping pigment. CONSTITUTION:The surface of a film base material 1 consisting for example of polyethylene terephthalate or the like is applied with an adhesive agent 3 blended with flare stopping pigment 2, and the conductive metallic foil 4 of a copper foil or the like is laid over the the adhesive agent 3 so as to be adhered to each other through heating and pressing them. The process, in which a printed-circuit board is manufactured from the flexible printed-wiring board 5, is the same as a conventional process. That is, after a photoresist is supplied on the surface of the conductive metallic foil 4, and exposed into a desired circuit shape, the etching of the metallic foil 4 is carried out so as to form a circuit, and a flexible printed-circuit board is made by removing the residual photoresist. In this fashion, flare stopping property is obtained, because the flare stopping adhesive layer is formed, and it may also be used as a flare stopping board, particularly, it is effective to be a circuit board constituting the electrical circuit of optical appliances.

Title: Frequency multiplier circuit
Inventor: TOMOTSUNE KATSUO
IPC: H03K5/00
Filed: 1988-08-12
Abstract: PURPOSE:To obtain a frequency multiplier circuit whose output duty is 50% by using a constant current source to charge/discharge of a capacitor, coupling an output triangle wave through a capacitor and amplifying the wave, and taking exclusive OR between an input signal and an output of the amplifier. CONSTITUTION:A capacitor 7 is charged/discharged by a constant current source 5, its output triangle wave is coupled by a capacitor and amplified by the amplifier 9 and exclusive OR 10 between the input signal and the output of the amplifier 9 is taken. Since the input waveform to the amplifier 9 is a triangle wave having a slope depending on the capacitance of the capacitor 7 charged/ discharged by the constant current sources 5, 6, the slopes are made symmetrically on the border of a threshold voltage VTR at the input of the amplifier 9 and the multiplied output is an output waveform whose duty ratio is 50%. Moreover, even if the constant current or the capacitance of the capacitor or the like have manufacturing dispersion, they have only to vary the peak value of the triangle wave and the symmetry of the slopes is not lost, the output duty is not subject to the effect but always 50%.

Title: Sheet transport device
Inventor: KAMANO TADAO
IPC: B41J13/00
Filed: 1991-08-12
Abstract: PURPOSE:To enable a sheet to be transported stably without loosening it by providing a means for absorbing the tension of a sheet which is capable of tolerating a specific value obtained based on the length of a sheet transport path at a ratio between the speeds of both transport rotors, and the offset of a position of the first transport rotor which is almost equal or larger in diameter in a sheet feed rotation direction, in the first drive transmission part. CONSTITUTION:A sheet P is fed to an image processing part 1 using the first transport rotor 11 capable of transporting the sheet at a speed of v1, and then is discharged using the second transport rotor capable of transporting the sheet at a speed of V2. The slack, if any, generated in the sheet P is eliminated at a ratio of v1<v2. In this case, given the ratio of the speeds of both transport rotors 11, 21 as k, the maximum length of the sheet transported as L1, and the length of a sheet transport path between both transport rotors 11, 21 as L, the offset of a position for the first transport rotor 11 in a sheet feed rotation direction is almost equal to or larger than the value given as (1-k).(L1-L). Therefore, a means for absorbing the tension of a sheet which tolerates the offset is provided in the first drive transmission part. Thus it is possible to transport the sheet, regardless of size and quality, stably without causing a slack.
